LocoMo'rivn-'rnnnna To aZZ rwhom it may concern.'

Be it known that I, NATHAN M. LOWER, a citizen of the United States, andresident of Schenectady, county of Schenectady, and State of New York,have invented certain vnew and useful Improvements inLocomotive-Tenders, of which the following is a specification, and whichare illustrated 1n the accompanying drawings, forming a part thereof.

The invention relates to locomotive tenders in which there is rovided afuel bin; its object being to provide improved means for advancing thefuel to the shoveling platform, where it will be within easy reach ofthe fireman. It consists i n providing such tender with one or morescrew conveyers located immediately above the lfuel-supporting walls ofthe bin, and with power means for operating such screw or screws.

1n the accompanying drawings- Figure l'is a detail plan view of the fuelbin of a tender;

Fig. 2 is a detail vertical longitudinal section thereof, partly inelevation; and

. Figs. 3 and 4 are details of the driving gear for o erating theconveyer screws.

The ten er shown is of that type in which the fuelbin is provided withan inclined slope sheet at its rearward end, and is supplemented by afuel-carrying deck back of the bin roper, but the invention isapplicable to ten ers provided with bins of different coniguration andwithout a supplemental deck.

The side walls of the fuel bin are represented at 10, 11, its bottom isshown at 12, and its slope sheet at 13. At 14 there is shown a fuel deckextending backwardly from the upper end ofthe slope sheet and providedwith a vertical back wall 15. The fuel is supported by the floor 12, theslope sheet 13, and the deckv Hoor 14. Mounted upon each of thesesupporting ioors are screw conveyers 16, 17, 18; as illustrated in Fig.1 four of each of these conveyers being shown. As many may be providedas may be deemed advisable. These conveyers are of the usual form, eachcomprising a shaft on which is mounted a spiral flange. The shaft ofeach conveyer is journaled in one or more brackets rising from thefuel-supporting wall with which the conveyer is associated, and forconvenience in driving the Specication of Letters Eatent.

conveyers of each set may be connected/by means of universal Joints orby means of simple gearing.

As shown, the rearward end of the shaft of the conveyer 18 is journaledin a bracket 19 rising from a plate 20 which may be secured to the iioor14 of the deck by any suit-f able means, and preferably extends theentire length of the conveyer to take the wear incident to the forwardmovement of the sheet and extending backwardly the entire length of theconveyer. The forward end of the shaft of the conveyer 16 is journaledyin a bracket 26, rising from a plate 27 suitably secured to the floor ofthe fuel bin and extending backwardly the entire ylength of theconveyer. The rearward end of the shaft of the conveyer 16 is preferablysecured to the forward end of the shaft of the conveyer 17 by auniversal joint 28.

The rearward end of the shaft of the conveyer 17 and the forward end ofthe shaft of the conveyer 18 are provided with bevel gears 29, 30, whichmesh with a similar gear 3l xed upon a shaft 32 extending Atransverselyacross the tender, and to Awhich power is applied for driving theseveral conveyers. Inasmuch as the direction of rotation of the conveyer18 is the reverse of that of the conveyers 16 and 17, its spiral langeisgiven a reverse direction relatively thereto. n,

A suitable motor is provided for driving the conveyers. Such a motor isconventionally shown at 33, andl as being located at the forward end ofthe tender, its shaft 34 extending backwardly and being provided with abevel gear 35 which meshes with a `pair of similar gears 36, 37, looselymounted lso wardly and in convenient reach of the {ireman, this rodactuating a shipper yoke 40 in engxagcment with the clutch.

here a plurality of sets of conveyers is employed, as shown, all aredriven by means of the single shaft 32.

In order to protect the gearing from the fuel the brackets 21 and 22take the form of a housing, including a cover plate 41.

When the tender is first loaded with fuel, the conveyer or conveyerswill be entirely submerged therein and by theiraction will advance thelower fuel stratum, the upper portion of the load settling down as thead- Vance movement is continued. The conveyers are preferablysuticiently close together so that substantially all of the fuel will becarried forward to the shoveling platform. Should any clogging occur thedirection of rotation of the conveyers may be reversed by shifting theclutch. The conveyers may be driven continuously, or may be operatedintermittently ,either by the motor or clutch control. 'Y

of construction is shown and described, various changes in detail may beintroduced without departing from the scope of the invention.
